| 摘 要： | 某连续梁桥桥宽36.0 m,采用双箱断面,两箱之间不设横隔梁,仅翼板连接。通过建立空间模型,分析了这种翼板连接宽桥的受力特点。理论分析和成桥试验均表明翼板连接箱梁与分离式双箱梁相比较,由于增加横向约束,挠度减少明显,整体受力性能较好。

| Abstract: | A continuous beam bridge has a 36.0 m wide deck with two box-girders whose flange is linked instead of crossbeam.Mechanic characteristics is analyzed on the bridges by building spatial models.Compared with seperated pair of box girder,the flange-linked bridge integrity is in good condition and its deflection is decreased obviously because of the increased lateral restraint,which was proved by theoretical analysis and bridge test. |

| Keywords: | continuous girder box girder cross girder flange plate connection seperation deflection |
